Geometry of 3D ray field and pulse propagation

Field computations in ray approximation perform mapping in 6D space of ray parameters (a,b,t) and spatial coordinates (x,y,z), where (a,b,t) are launch angles in the source and t-eikonal. In the case of 2 spatial dimensions, mapping occurs in 4D space. This work investigates properties of such mappings, which allow a robust search of eigen-rays and modeling of pulse propagation
